Descriptions

iXsystems TrueNAS CORE tarfile.extractall Directory Traversal Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of iXsystems TrueNAS devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the tarfile.extractall method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root. Was ZDI-CAN-25626.

Vulnerabilidad de ejecución remota de código mediante el método tarfile.extractall de iXsystems TrueNAS CORE. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en instalaciones afectadas de dispositivos iXsystems TrueNAS. No se requiere autenticación para explotar esta vulnerabilidad. La falla específica existe dentro del método tarfile.extractall. El problema es el resultado de la falta de validación adecuada de una ruta proporcionada por el usuario antes de usarla en operaciones con archivos.
